Carbon concrete polyacrylonitrile (PAN)/lignin-based carbon fiber (CF) composites are a new promising material class for the building industry. The replacement of traditional heavy and corroding steel reinforcement by (CF)-based reinforcements offers many significant advantages: higher protection environmental resources because lower CO2 consumption during cement production, longer lifecycle thus, much less damage to structural components degree design freedom lightweight solutions can be...
Several studies have shown the importance of carbon fibres (CF) for different high technology markets. In recent years, fibre types with improved properties been developed those Polyacrylonitrile (PAN) copolymers are basic raw material (precursor) these in predominant case. Improvements mechanical mainly achieved by defect reduction during manufacturing process. Thus, commercial tensile strengths up to approx. 7000 MPa currently available. It can be that further increased (in direction...
The building sector accounts for approx. 40% of total energy consumption and 36% all greenhouse gas emissions in Europe. As the EU climate targets 2030 call a reduction by more than half compared to 1990 also aim neutrality 2050, there is an urgent need achieve significant decrease use buildings towards Nearly Zero-Energy Buildings (nZEBs). footprint includes both construction phase during service life, nZEB solutions have provide energy-efficient less carbon-intensive materials, specific...
Carbon concrete PAN/lignin-based CF composites are a new promising material class for the building industry. The replacement of traditional heavy and corroding steel reinforcement by carbon fiber (CF) based reinforcements offers many significant advantages: higher protection environmental resources because lower CO2 consumption during cement production, longer lifecycle thus muss less damage in structural components degree design freedom lightweight solutions can be realized. However, due to...
While carbon fibers (CFs) are still the most attractive reinforcement material for lightweight structures, they mostly manufactured using crude oil-based process chains. To achieve a higher eco-efficiency, partial substitution of polyacrylonitrile (PAN) by renewable materials, such as lignin, is investigated. So far, this investigation has only been carried out batch manufacturing studies, neglecting transfer and validation to continuous CF manufacturing. Therefore, work first investigate...
Abstract Kohlenstofffasern sind aufgrund ihrer hohen massespezifischen mechanischen Belastbarkeit ein unverzichtbarer Werkstoff im Leichtbau. Diese werden mittels eines zeitaufwendigen, thermooxidativen Stabilisierungs‐ und inerten Carbonisierungsprozesses hergestellt. Bedingt durch die kommerziell dominierte Forschung basiert der Großteil veröffentlichten Optimierungsansätze für diese Prozessschritte bis heute auf unvollständigen, empirischen oder nicht‐parametrischen, datengetriebenen...
Abstract Within carbon fiber manufacturing, the stabilization process is most time‐ and energy‐intensive due to complexity of chemical structure transformation. Therefore, optimization strictly required enable cost‐efficient processes. For first time, a hybrid semi‐parametric model for continuous developed prognose progress density stabilized fiber. The proposed takes parameters like dwell temperature, stretching as well precursor properties, such density, into account. Finally, offers novel...
For several decades, carbon fibers have been used for lightweight engineering in aircraft automotive and sports industries, mostly based on high-quality polyacrylonitrile (PAN). We investigated a novel PAN-based precursor fiber (PF) modified with polycyclic aromatic hydrocarbon, namely hexabenzocoronene (HBC), which is expected to improve the thermal conversion process create (CF) enhanced mechanical properties. this purpose, PF spun-like homopolymeric were thermally stabilized carbonized...
Abstract The present study investigates the influence of modification temperature and dose rate electron on progress these three important thermal induced reactions namely: cyclization, dehydrogenation, oxidation. Since chemical strongly depend polymer chain segment mobility, temperatures below glass transition ( T g ) above are tested. Electron paramagnetic resonance (EPR) spectroscopy measurements show presence alkyl‐, peroxy‐, polyimineradicals alongside each other. Gel identified a...
In carbon fiber (CF) production, the stabilization process step is most energy- and time-consuming in comparison with carbonization graphitization. To develop optimization routes for energy productivity, needs to be monitored continuously via inline analysis methods. prognose evolution of high-performance CF, density stabilized fibers has been identified as a robust pre-indicator. As offline not feasible analysis, density-soft sensor based on indices Fourier Transform Infrared spectrum...
